, To all whom t may concern:

Be it known that I, JOSEPH S. WILLIAMS, a citizen of the United States, residing at Riverton, county of Burlingtor, State of New Jersey, have invented a new and useful Resilient-Tire Construction and Wheel Equipment, of which the following is a specification.

My invention consists of a novel construction of a resilient tire and wheel equipment which will give in. practice marked and advantageous results, provision being made for reinforcing the construction to any desired extent;

It further consists of novel features of construction, all as will be hereinafter fully set forth. j

For the purpose -of illustrating my invention, I have shown in the accompanying drawings those forms which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, `although it is to be understood that the various instrumentalities of whichmy inventionconsists can be variously sections of the embodiments seen in Figs.

1, 2 and 3, respectively.

Figs. 10, 11 and 12 represent longitudinal sections of the constructions seen in Figs. 1, 2 and 3, respectively.

Figs. 13 to 22 inclusive, represent transverse sections of other embodiments of myl invention.

Similar numerals of reference indicate corresponding parts in the figures.

Referring t0 the drawings.

Y In all the vembodimentsof my invention herein shown, I have illustrated a construction in which a resilient reinforcement is circumferentially and transversely disposed between the rim and the tread.

Referring rst to Figs. 1, 2 and 3, an

annular resilient core constructiony is provided which is transversely elongated or of elliptical or flattened construction in. cross Section with annular metal reinforcements 34 in the seating parts and flexible metal 35 supporting the outer face of the solid cushioning cores 36 which are designed to be compressible and provide support without theuse of fluid content or by means of fluid content in the transversely disposed inflatable tube 37. Such fluid content may be of elastic or incompressible nature or of viscous material and the position of the tube under fluid content is indicated at 38 in Figs 10, 11 and 12.

The transversely elongated arrangement.

of the vresilient cores 36, tensile and flexible metal 35, inatable tubes 37 and luid`content 38 are embodied as a unit of construction within an outer casing 39 which is circumferentially inextensible and is of elongated or flattened form in transverse section. Detachable and demountablen tire equipmentsv are provided having rings 40 and 41 which grip' the seatings of the con struction and hold the same under compression in firm wheel equipment under all conditions of inflation andV deflation. The core 36 in Fig. 1 is formed of resilient rubber or a mixture of rubber and any other desired material reinforced transversely by fabric or fiber 42. The tensile and flexible metal 35 has a layer of tensile cushioning material 43 on the outer face thereof to serve as a cushioning layer and a bond between the member 35 and the tread portion of the outer casing 39 and to obviate the strain thereon and on the fibrous reinforcement 44 as the member 35 responds to the deflected action of load strain and vinequalfY ties of the road surface. 45 designates a fluid `tight liber and rubber tube incasing the core 36 and is transversely disposeCL and of flattened elliptical formation in cross section. The seating parts of the outer 'casing 39 are reinforced by annular members 47 and 48 preferably of metal which extend into the channel seating between and formed by the clencher rings 40 and 41 which latter are seated upon the rim tire 49. 50 'designates an outwardly extending annular flane at one side of the rim 49, the opposite fs-i e being provided with an inwardly extending annular flange 51 with which interlocl'ts the transversely divided 'locking ring 52 which forms a supporting or retaining member for thel ring 41 which when forced transversely toward the ring impresses the elastic parts of the seatings so that the tire will be firmly gripped and retained under compression in wheel equipment.

Any desired type of inlet passage may be provided with the conventional type of valve mechanism.

In the embodiment seen in Fig. 2, the core has a flattened formation instead of the flattened arch formation seen in Fig. 1. rI`he demountable ring 53 is formed of two annular transversely divided rings 54 and 55 each of which are provided with circumferential locking parts at 56 to form when united the demountable-rim 53. 57 and 58I designate annular projections co-itting and interlocking in the annular groove of the rim- 49.v

In the embodiment seenv in Fig. 3, the terminals 59 and 60 are in engagement with the seating members 34 and 61 and the clencher rings 62' and 63 which latter are clamped to the rim 64 by bolts 65.

In the embodiment seen in Fig. 4, the core construction 36 is enveloped by a fluid-tight tube 66 conforming to the outer contour of the core 36 and the inner periphery of the outer casing 39. The terminals 39 and extend over the reinforcing member 34 so that the core is provided with a seating throughout its width. The terminals of the outer casing 39 are provided with annular reinforcements 47 and 48. Such terminals are located in the annular channel formed by the clencher member 70. rIhe outer face l of the casing 39 is provided with annular grooves 72 with which interlock annular projections 73 of a detachable tread 67 against which the outer casing 39 is held 1n compressive engagement. In some cases it lis advantageous to employ an annular and transversely disposed resilient reinforcing member 74. The detachable tread is provided with annular reinforcements 7 5 and with an annular tensile and flexible reinforcing member 76 covering the width of the cushioning core 36. The inner channel space of the member 69 is seated on the rim 49 and locked in position by the projections 68 and 70 on the inside face of the member 69. 71 designates bolts passingA radially through the rim 64, the rim 49, the annular member 69 and into the annular member 34 so that the terminals 39 and 60 are compressed thereby and all the parts united i-n wheel equipment.

In the embodiment seenin `Fig. 5, 70 is the cushion core seated upon the mountable rim member 69 which is channeled on its inner face to interlock with the rim 49. rIhe core 70 is located in the outer channel part of the member 69 and the covering of the core has an annular band of tensile and flexible metal 71 which renders divided channel 'from the core 36' messes such portion circumferentially inextensible. This member 71 is located within the outwardly projecting sides of the seating member 69 so that the tire construction is firmly secured in position and reinforced against torsional strain and uniformly supported throughout the width of the core. The outer face of the core covering is equipped with a detachable tread 67 interlocking in the samemanner as the detachable tread seen in Fig. 4.

In the embodiment seen in'Fig. 6, the demountable member 69 corresponds in construction and is secured in position in the same manner as that seen in Fig. 5. In addition to the annular reinforcing member 34', annular reinforcements 47 p and 48 may be employed.

My invention' may be employed either with or withoutfiuid Content and in Figs. 7, 8 and 9, I have shown the fluid content as being omitted while in Figs. 10, 11 and 12, the fluid content is employed..v

In the embodiment seen in Fig. 13, the transversely arranged core 36 has an annular metal member 35 of steel or other metal of elliptical form in cross section filled with rubber or a mixturezof rubber transversely reinforced by fibrous or other material 77 surrounded by fabric or rubber structure 66 which latter is ,mounted upon an annular seating member 79 having inwardly projecting anges extending -into the seating part which is adapted to be received and rest upon the rim'and be secured thereto in any desired manner. The core and the other parts just described are enveloped by the outer covering 39 which is provided with a flattened tread.

In the embodiment seen in Fig. 11, the outer casing has a flattened tread andis under radial compression in the transversely member 69, a metal reinforcement 78 being provided and the seat-4 ing member 69 having an annular projection 83.

In the embodiment seen in Fig. 15, the resilient core 36 has an nnular flexible metal member 79 approximating the width of the core and a portionof the core covers the outer face of such `member which is provided with a cushioning layer 43 on its outer face. This core is enveloped by fabric lay- 'ers 66 corresponding to the outer form of the core 36 which latter is backed by the reinforcing member' 8O having inwardly projecting `iianges 81 with which cofit the transversely divided demountable rim 69.

In the embodiment seen in Fig. 16, reinforcements 7 9 are shown having inwardly extending flanges extending into the seating parts of the transversely divided annulus 69.

rlhe outer casing 39 may be detachable and operate as ,an 111- wardly opening construction and be combinedvwith an annular transversely divided member 84 as seen in Fig. 17, in which metal reinforcements 86 and 87 overlap and interlock with the member 84.

In the embodiment seen in Fig. 18, outer and inner annular members 88 and 89 are provided with resilient cushioning material 36 or mattress 36' between the members 88 and I89 or the channels formed therein. The outer casing 39 colits and is seated upon a demountable member 84. A detach Iable tread with inwardly extending side flanges is interlocked with the casing 39.

In the embodiment seen in Fig. 19, the tire body is mounted on or formed with an annular metal member 92 exterior of which is the tire body 91 which is adapted to interlock With a detachable tread, While in the embodiment` seen in Fig. 2O the detachablel tread has been omitted.

In the embodiment seen in Fig. 21, the construction corresponds substantially to that seen in Fig. 16 except that a rim equip ment corresponding to that seen in Figs. 19 and 2O is employed instead of the rim equipment seen in Fig. 16.

In the embodiment seen in Fig. 22, the tire body 91 is mounted on a'transversely arranged core 36 seated in the channel of the annular member 493 which latter is seatif ed upon a attened annular cushion 365 mounted on the transversely divided demountable member 94 which interlocks with the rim equipment. |The tire body 91 is provided With an annular reinforcement 92 which is within the ends of the outwardly extending flanges of the member 98.

In accordance with my present invention, an annular' and transversely .elongated body is provided which forms a non-collapsible and universal resilientl truss. The flexible tension elements of the truss are annularly and transversely disposed and are arranged substantially concentric relatively to the major transverse .axis of the construction and preferably on both sides of such axis,

with curvatures at the sides forming iiexing [tension abutments for the annular transverse truss or trusses of the tension elements. I also employ an annular and transversely elongated cushion in abutting relationship with the annular and transverse tension truss or trusses. The curvatures at the sides of the tension belt formed by the tension truss or tension element are yieldingly supported by the flexible cushioning material which substantially fills the space between said curvatures, and the cushion is in abutting relationship with the annular andA transverse tension truss throughout the length and width of the construction.

forni of 'a tension belt, may be increased by introducing fluid under pressure into the tage enumerated as desirable in the state-- ment of the invention and the above description, and While I have, in the present instance shown and described preferred embodiments thereof which have been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars Without departing from the spirit or scope of the invention or sacrificing any of its advantages.
